“I see solar becoming the new king of the world’s electricity markets. Based on today’s policy settings, it is on track to set new records for deployment every year after 2022,” said Dr. Fatih Birol, the IEA Executive Director. “If governments and investors step up their clean energy efforts in line with our Sustainable Development Scenario, the growth of both solar and wind would be even more spectacular – and hugely encouraging for overcoming the world’s climate challenge.”
Renewables take starring roles in all our scenarios, with the solar center stage. Supportive policies and maturing technologies are enabling very cheap access to capital in leading markets. Solar PV is now consistently cheaper than new coal- or gas-fired power plants in most countries, and solar projects now offer some of the lowest-cost electricity ever seen. In the Stated Policies Scenario, renewables meet 80% of global electricity demand growth over the next decade. Hydropower remains the largest renewable source, but solar is the main source of growth, followed by onshore and offshore wind.
In the Stated Policies Scenario, which reflects today’s announced policy intentions and targets, global energy demand rebounds to its pre-crisis level in early 2023. However, this does not happen until 2025 in the event of a prolonged pandemic and deeper slump, as shown in the Delayed Recovery Scenario. Slower demand growth lowers the outlook for oil and gas prices compared with pre-crisis trends. But large falls in investment increase the risk of future market volatility.
